Write in vertex form<br> f(x)=x^2+12x+34
svp [43]

Answer:

(-6, -2)

Step-by-step explanation:

f(x) =  {x}^{2}  + 12x + 34

= f(x) =  {1x}^{2}  + 12x + 34

= a = 1, b = 12

= x =  -  \frac{12}{2 \times 1}

= x =  -  \frac{12}{2}

= x = -6

= f(x) =  {x}^{2}  + 12x + 34.. =  - 6

= f( - 6) =  - 2

= (-6, -2)
